This isn't necessarily a new technique, as black and white art has been put on floppies before: https://github.com/bzotto/picturedsk

But the new wrinkle here is support for grayscale, meaning photos or other grayscale artwork can now be put on a disk.

We can even put the art inside of valid sectors to keep the disk appearing completely normal to casual observation from a host computer.

But how do you hide the floppies?

Just having that media would be suspicious in and of itself...

Using the Green channel instead of the Red is much more likely to make a good looking grayscale image.
